Magnet tire

ABSTRACT

A magnet tire adapted for use on a wheel designed for use with a conventional pneumatic rubber tire, in which the magnetic zones are formed along the inside face of the tire tread and along the tire mounting face of the rim, respectively, such that said zones are opposed to each other, with their opposed faces having magnetism of same polarity.

BRIEF DESCRIPTION OF THE PRIOR ART Most of the conventional rubber tiresof this type are used with air pumped thereinto through or without themedium of an inner air-tube. According to such conventional tires,however, the tread tends to shrink toward the center whenever load isgiven thereto, so that it was difficult or almost impossible for avehicle carrying such tires to run along a snow-laden road, a muddy roador a sandy way. Further, in case a wheel of the vehicle should fall intoa ditch or a depression, the tire on that wheel may be deformed by theimpact, causing the rim to crash against a corner of the ditch or otherobject to let it suffer damage.

The present invention is to provide an improvement in such tires so asto eliminate the defects, such as mentioned above, which accompany theconventional tires.

BRIEF DESCRIPTION .OF THE DRAWING The sole FIGURE of the drawing shows atransverse sectional view of a magnet tire according to the presentinvention.

SUMMARY OF THE INVENTION This invention relates to a rubber tire for usein a surface-running vehicle such as automobile, and more particularlyit relates to such rubber tire adapted to be mounted on a wheel designedfor use with a conventional pneumatic rubber tire, in which the magneticstrips are provided, in opposed relation to each other, on the insideface of the tire tread and on the tire mounting face of the rim,respectively such that their opposed faces will have magnetism of samepolarity, whereby to eliminate the troubles accompanying theconventional tires, such as mentioned above.

The invention will now be described in detail by way of its embodimentwith reference to the accompanying drawing. Referring to the drawing,there is shown part of a rubber tire, generally designated 1, which hasattached thereto a rim 2 of a wheel adapted for fitting said tire lthereover. Along the inside surface of the tread of said rubber tire Iis fixed a magnet belt 3 by means of an adhesive. There is also provideda similar magnet belt 5 fixed, as by an adhesive, along the tiremounting face 6 of said rim 2. Said both magnet belts 3 and 5 are soadapted that their opposed faces will bear magnetism of same polarity,and that said magnetism will be of such intensity as will produce mosteffective repulsion according to the distance between said both magnetbelts 3 and 5.

Although magnet belts are used in the embodiment shown, the magneticmeans used on the inside face of the tire tread and on the tire mountingface of the rim may be provided by magnetizing the tread and the rimthemselves, or other various suitable methods may be employed withoutdeparting from the scope of the present invention. It may also beunderstood that the present invention finds may applications for varioustypes of tires, whether tube or tubeless.

Thus according to the present invention, a pair of magnet belts areprovided in such a manner that their opposed faces have magnetism ofsame polarity, so that due to joint action of air pressure and magneticpressure produced in the vertical direction by the repelling forcebetween the magnet belts relative to the groundengaging face of thetire, greater restorability is obtained than that of a conventional tirewhere air alone is pressed in. This enlarged restorability providesresistance against deformation of the tread by loading, thus enablingthe vehicle to run along a bad road, such as a snow-laden road, mire orsandy road. Further, in case the car is mired in a ditch or a depressionin the road and the tire is deformed upon receiving momentary impact tocause approach of the tread to the rim surface, the magnetic repulsionbetween the magnet belts is increased in proportion to the degree ofapproach of the tread to the rim surface, thus preventing them fromcoming into contact with each other so as to preclude any possibility ofcausing damage to the rim. Thus, the

present invention provides a novel tire having excellent cushioningproperty and high stability.

What I claim is:

1. In a tire with a tread, a rim, and a wheel combination wherein arubber tire is fastened to a wheel rim by mounting said tire on the tiremounting face of said rim, the improvement therein wherein a firstmagnet belt is affixed to the inner peripheral surface of said tiretread posed faces will have magnetism of the same polarity. 3 *k

1. In a tire with a tread, a rim, and a wheel combination wherein arubber tire is fastened to a wheel rim by mounting said tire on the tiremounting face of said rim, the improvement therein wherein a firstmagnet belt is affixed to the inner peripheral surface of said tiretread and a second magnetic belt is affixed to the outer peripheralsurface of said tire mounting face concentric with said first magneticbelt so that the inner face of said first belt faces the outer face ofsaid second belt, said belts being so arranged and disposed that theiropposed faces will have magnetism of the same polarity.
